概括

前列腺MRI中的加速T2映射提供了定量生物标志物,用于区分良性和恶性病变. 109.2毫秒的门可以帮助诊断,可能改善自动化病变检测.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
在瘤学瘤学.

背景情况:

标准化多参数前列腺MRI (mpMRI) 报告使用Pi-RADS,但定量测量缺乏可比性.
T2映射提供可重复的定量成像生物标志物,但往往耗时.

研究的目的:

评估一个高度加速的T2映射序列用于前列腺MRI中的定量测量.
使用T2映射建立一个值来区分良性和恶性前列腺病变.

主要方法:

54名患有活检确认前列腺癌或排除前列腺癌的患者的回顾性研究.
利用一种新的,高度加速的T2映射研究序列用于高分辨率成像.
使用REML的线性混合效应模型来比较癌症和健康组织之间的T2值.

主要成果:

在恶性病变 (平均T2: 80.9毫秒) 和正常组织 (平均T2: 151.7毫秒) 之间观察到显著的差异化 (p < 0.001).
确定了109.2毫秒的T2切断值,以区分恶性和非恶性区域.
在外围区域T2值和PI-RADS得分之间发现了显著的相关性 (p = 0.0194).

结论:

加速T2映射使前列腺组织的有效量化评估成为可能.
确定的109.2毫秒的值可以区分恶性和良性前列腺病变.
将T2映射集成到常规的mpMRI中可以增强自动化病变检测并促进无对比度成像.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
